A copy of the underlying view.

Example

Run this code 
#include <iostream>
#include <ranges>
namespace stq {
void println(auto, const auto& v)
{
    for (const auto& e : v)
        std::cout << e << ' ';
    std::cout << '\n';
}
}
int main()
{
    static constexpr int a[]{1, 2, 3, 4, 5};
    constexpr auto view = a | std::views::take_while([](int x){ return x < 4; });
    stq::println("{}", view);
    const auto base = view.base();
    stq::println("{}", base);
}

Output:
